Perfect storm opens Reliant's roof

1 / 81

Back to Gallery

Back in the day, the Reliant Stadium roof was routinely open for Texans games — the team is 23-19 overall in games played under the Texas sky — but Sunday night marked the first time since the Texans beat Jacksonville 24-14 on Oct. 30, 2013.

A combination of factors came into play in the decision. It was a perfect fall night — the temperature at kickoff was 61 degrees — and NBC obviously preferred being able to do overhead shots with the field visible and the Texans weren’t exactly on a roll with the roof closed, having been pounded by the Rams 38-13 in their last Reliant appearance.

Also, quarterback Case Keenum, who was making his first start at home, has rarely played in a closed environment and thus had no special affinity for it.
